EXT3-fs: unable to read superblock after kernel upgrade
 

Hi
anyone know how to handle this :

After upgrading (with up2date) to kernel 2.4.20-13.8smp, from 2.4.18-27.8.0smp,
same after upgrading to 2.4.20-18.8
the system won't boot these versions.
Version 2.4.18-27.8.0smp and older, boots fine from grub.
Boot errors:
Mounting root filesystem
EXT3-fs: unable to read superblock
mount: error 22 mounting ext3
pivotroot: pivot_root(/sysroot,/sysroot/initrd)failed
unmount /intrd/proc failed
Kernel Panic, system hangs etc etc

tried booting with and withouth directory /initrd

I use, ext3 on a mirror fs /dev/md0 for boot and md1 for root
labeling the disks with e2label (/ and /boot) makes no sence.
System is running fine with 2.4.18-27.8.0smp !

hope someone understand this

Do you have initrd files for the kernel versions you're trying to install?

yes, they are all there, for each version in grub.conf
